2.Application and advantage :
Application: Wollastonite can be widely used in construction field,brake linning,insulation field etc.
wollastonite fiber,especially dedicated to high-end friction materials,can greatly increases wear and heat resistance of friction materials by its acicular shape and unique physical property. The frictional flexibility and stability of friction materials can be improved when filled up by wollastonite fibrous products.
Wollastonite can substitute asbestos in friction and braking field as friction coefficient increases when wollastonite is added into friction materials. In this case, brake flexibility improves, wear rate decreases, and performance is stabilized without creating noise or scratching dual. At the same time,being innocuous and harmless, wollastonite is environmentally protective.
Being innocuous, flavorless, and non-radioactive, wollastonite can totally substitute for asbestos and partially for fiberglass.It can be new environmental building materials as it reduces pollution and production cost without degrading performance of building products.
Wollastonite fiber’s application in building materials such as calcium silicate board with microporous, fiber cement board, fireproofing insulation board, proves to be very mature. It dramatically increases shock resistance, flexural strength, and abrasive resistance of the building products , which are featured with corrosion resistance, sound and heat insulation, and fireproofing.
The granularity of wollastonite fiber for building use ranges from 100 to 800 meshes. The granularity, aspect ratio and purity determine its application in different types of building products.
